9=sqrt((5+x)^2-x^2)

9 = (5 + x)^{2} - x^{2}

x = \frac{28}{5}

Decimal Notation

x = 5.6

Solution steps

9 = (5 + x)^{2} - x^{2}

Square both sides:

81 = 25 + 10 x

81 = 25 + 10 x

Solve

81 = 25 + 10 x : x = \frac{28}{5}

x = \frac{28}{5}

Verify Solutions:

x = \frac{28}{5}

True

The solution is

x = \frac{28}{5}

(\frac{x}{1 - x})^{0.88} = 1.865

(x)^{2} = \frac{- x - 3}{2}

x, v = gx

x - 2 = x - 4

x + x - 16 = 2
